Make sure you're looking at the errata. The important point there being the hit points don't stack. This was kind of a big issue in our campaign.

Wait, so are you asking if a fighter, not trained in endurance would get the temp hp from the battlerager power? If so I'd say yes... you wouldn't get the invigorating temp hp of course but the power is still has the keyword even if you don't qualify for the bonus.

No was was asking about the temporary hit points granted by the combination of endurance and the invigorating keyword, and how they interact with the temporary hit points granted from the Battlerager vigor class feature.

Is that based on an expectation on how the rules should work? Or on interpreting invigorating temp hp as being a "normally granted by the power", or from another rule or ruling?
